Unity Linux 20.1070e Security Update: kernel (UTSA-2026-131765)

medium Nessus Plugin ID 366564

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-131765 advisory.

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: cancle set bad inode after removing name fails

The reproducer uses a file0 on a ntfs3 file system with a corrupted i_link.
When renaming, the file0's inode is marked as a bad inode because the file name cannot be deleted.

The underlying bug is that make_bad_inode() is called on a live inode.
In some cases it's icache lookup finds a normal inode, d_splice_alias() is called to attach it to dentry, while another thread decides to call make_bad_inode() on it - that would evict it from icache, but we'd already found it there earlier.
In some it's outright we have an inode attached to dentry - that's how we got it in the first place; let's call make_bad_inode() on it just for shits and giggles.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
